WESLEY COLE, OF MEN OMONEE, WISCONSIN.

WAGON-BOLSTER SPRING.

SPECIFICATION forming part of Letters Patent No. 290,860, dated December 25, 1883.

Application filedMarcl123, 1888. (No model.)

To all whom, it may concern:

Be it known that I, WESLEY COLE, a citizen of the United States, residing at Menomonee, in the county of Dunn and State of \Viscousin, have invented certain new and useful-Improvements in Wagon-Bolsters; and I do declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a side view of my bolster. Fig. 2 is a top View, and Fig. 3 is an enlarged cross-sectional view, of the same.

This invention has relation to wagon-bolsters; and it consists in the construction and novel arrangement of parts, as will be hereinafter fully described, and particular pointed out in the claim appended.

In the accompanying drawings, the letter A designates a wagon-bolster having the guide standards B, which are faced on their inner edges, preferably as shown, in order to avoid undue wear.

0 represents the transverse movable barbearing on which the box or bed rests. The bar 0 is formed with recesses in its ends, as indicated at d, said recesses being designed to engage the standards 13. Usually the ends of the bar 0 are faced with metallic wearplates e.

To the bolster A, near each end, is secured a saddle-plate, F, the middleportion, g, of which is raised in rectangular form, so that it will, when seated on the bolster, engage its sides and upper surface. At each end the saddle-plate F carries an upwardly-extending tubular sea-t, h,which rises from an outwardlyturned flange-bearing, k, extending from the lower end of the vertical side portion, Z, of the saddle-plate, and forming the bottom of the tubular seat h.

To the bearing-bar 0, near each end, over the bolster saddle-plate, is secured a saddleplate, G, the middle portion,m, of which is depressed in rectangular form to receive the bearing-bar, which is designed to fit snugly between the sides and bottom of the depressed portion. From the upper ends of the sides I of-the depressed portion extend outward flange-bearings k, from which extend downward tubular caps h, which are of larger diameter than the tubular seats h of the lowor saddle-plates, and are of sufficientlength to extend down around the seats 11, inclosing and protecting said seats h and the springs s therein. A perforation, 1), is made in the top of each captube 71.. The springs s are pret erably of spiral form, and are of suificient power and length to support the load on the wagon. Sometimes it is designed to arrange within the large spring a smaller and lighter spring, adapted to carry the wagon-box,when not loaded, in a light and yielding manner.

Secured to the bottom of each base-tubeh isa centrally-arranged upright link, 22, and in connection with this link is an upper link, 1), which is formed with a threaded projection, 25, which extends upward through the perforation 10 in the top of the cap-tube and is secured by means of a nut, n.

The tubular base-seats h are preferably made shorter than the vertical side walls of the saddle-plate, to which they are attached, while the cap-tubes h are of greater length, extending much below the upper saddle-plates.

The springs are designed to be loosely packed with cotton saturated with coal-oil, in order to prevent them from breaking in cold weather.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

The combination,with the bolster and a movable bearing'bar above the same, of the saddleplates carrying, respectively, the base-tubes and cap-tubes, the springs inclosed within said tubes, and the slide link connections between the base-tubes and cap-tubes, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

WESLEY COLE.
